WHAT IT DOES

What neuron_create_group does on Neuron

AI agents use neuron_create_group to create or update resources in Neuron, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Neuron environment.

Parameter	Type	Required	Description
`slug`	string	—	Optional org-unique handle (lowercase letters, numbers, hyphens)
`tags`	array	—	Keep only contacts carrying one of these tags
`phones`	array	—	Raw phone numbers, e.g. pasted from a CSV
`listIds`	array	—	Contact list ids or slugs — pulls every member
`subject`	string	Yes	Group name
`ifExists`	string	—	When the slug is already taken: 'error' (default) fails, 'return' returns the existing group and adds any given members to it (idempotent create).
`channelId`	string	—	Session (connected WhatsApp number) UUID. Omit to use the default.
`contactIds`	array	—	Existing contact ids
`allContacts`	boolean	—	Union the org's entire address book
`description`	string	—	Optional group description
`fromGroupIds`	array	—	Copy/combine members live from these WhatsApp group JIDs
`excludeListIds`	array	—	Subtract every member of these lists

Parameters from the server's own tool schema.

RISK

Why neuron_create_group is rated Medium

An AI agent can call neuron_create_group faster than any human can review: one bad instruction and it creates or modifies resources in Neuron by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs neuron_create_group safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Neuron, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For neuron_create_group, this is the rule to start with:

neuron_create_group Rate-limited

neuron_create_group stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Neuron, apply this rule, and every neuron_create_group call is checked against it from then on.

FAQ

Questions about neuron_create_group

What does the neuron_create_group tool do? +

Create a new WhatsApp group and seed its members from any combination of sources: other groups (combine/copy), contact lists, individual contacts, pasted phone numbers, or the whole address book. Optionally pass a unique slug to address the group later without its JID. Members blocked by privacy come back in the failed list. Uses the org's default connected session unless channelId is given. It is categorised as a Write tool in the Neuron MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does neuron_create_group accept? +

neuron_create_group accepts 12 parameters: slug, tags, phones, listIds, subject, ifExists, channelId, contactIds, allContacts, description, fromGroupIds, excludeListIds. Required: subject. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on neuron_create_group? +

Register the Neuron MCP server in PolicyLayer and add a rule for neuron_create_group: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Neuron. Nothing to install.

What risk level is neuron_create_group? +

neuron_create_group is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit neuron_create_group? +

Yes. Add a rate_limit block to the neuron_create_group rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block neuron_create_group completely? +

Set action: deny in the PolicyLayer policy for neuron_create_group. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides neuron_create_group? +

neuron_create_group is provided by the Neuron MCP server (neuron-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
